... and late night television's never been the same. Johnny Carson's
last day as host of The Tonight Show. The video below is actually
from the night before, but it's the one most people as Johnny's official
"farewell."

(YouTube video. From the description: Bette Midler singing "One For
My Baby (And One For The Road)" on Johnny Carson's final show with guest
appearances (1992). On May 21, 1992, the eve of Johnny Carson's last
show, he hosted his final guests, Robin Williams and Bette Midler. It
was also the final show before a regular studio audience; fans, who had
been camping out to get into the final shows, waited up to 35 hours to
get into this one. Once underway, the atmosphere was electric and Carson
was greeted with a sustained, two-minute ovation at the start. Williams
displayed an especially uninhibited take on his trademark manic energy
and stream-of-consciousness lunacy. Midler, in contrast, found the
emotional vein of the farewell. When the conversation turned to Johnny's
favorite songs- "I'll Be Seeing You" and "Here's That Rainy Day" --
Midler mentioned she knew a chorus of the latter. She began singing the
song, and after the first line, Carson joined in and turned it into an
impromptu duet. Midler finished her appearance from center stage, where
she slowly sang the pop standard "One for My Baby (and One More for the
Road)". Carson became unexpectedly tearful, and a shot of the two of
them was captured by a camera angle from across the set which had never
been used before. The audience became tearful as well, and called the
three performers out for a second bow after the show completed. This
penultimate show was immediately recognized as a television classic, and
Midler would consider it one of the most emotional moments of her life
and would win an Emmy Award for her role in it.)
